## 4. Data Structures

### 4.1 Directory Lease Context
```java
package jcifs.internal.smb2.lease;

public class DirectoryLeaseContext extends Smb2LeaseContext {
    public static final String NAME_DIRECTORY_REQUEST = "DLse";

import jsinterop.annotations.JsOptional;
import jsinterop.annotations.JsPackage;
import jsinterop.annotations.JsType;
import org.jspecify.annotations.Nullable;

/**
 * Java super source for ListenableFuture, implementing a structural thenable via a default method.
 * For restrictions, please refer to the documentation of the then() method.
 */
public interface ListenableFuture<V extends @Nullable Object> extends Future<V>, IThenable<V> {

#include "tensorflow/core/platform/types.h"
#include "tensorflow/core/public/session.h"

namespace tensorflow {
class Device;
class DeviceMgr;
class ServerInterface;
}  // namespace tensorflow

// Internal structures used by the C API. These are likely to change and should
// not be depended on.

struct TF_SessionOptions {
  tensorflow::SessionOptions options;
};

  tensorflow::Session* session;

## Importar `Header`

Primero importa `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declarar parámetros de `Header`

Luego declara los parámetros de header usando la misma estructura que con `Path`, `Query` y `Cookie`.

Puedes definir el valor por defecto así como toda la validación extra o los parámetros de anotaciones:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[9] *}

        That's a lot of work they are doing, but if more FastAPI users came to help others like them just a little bit more, it would be much less effort for them (and you and me 😅).

        By asking questions in a structured way (following this) it will be much easier to help you.

        And there's a high chance that you will find the solution along the way and you won't even have to submit it and wait for an answer. 😎

## Ejemplo

Para un ejemplo simple, consideremos una estructura de archivos similar a la descrita en [Aplicaciones Más Grandes](../tutorial/bigger-applications.md){.internal-link target=_blank} y [Testing](../tutorial/testing.md){.internal-link target=_blank}:

```
